Problems solved by technology

[0003] However, due to the similar structural characteristics of ASA and ABS (micron-sized rubber "sea islands" dispersed in the plastic continuous phase), the unprocessed ASA films currently on the market are all opaque films, which can only use plastic toner Single coloring, can not be printed in color like PVC film, which undoubtedly restricts the application of ASA film in the field of decoration to a large extent

Abstract

The invention provides water-based ink emulsion resin and a preparation method thereof. Through a special optimized emulsification scheme and process control, the emulsion polymerization process is stable and controllable, no filter residues are left after a reaction, and problem in polymerization stability of emulsions with high acrylonitrile monomer contents are solved. An emulsion obtained in the invention is fine in particle size and narrow in particle size distribution, which is beneficial for the preparation of subsequent intaglio printing water-based ink; the emulsion has very strong bonding fastness to an ASA / ASA composite system, and the peeling strength of a blank film sample can be improved to two times or more; and the emulsion has good adhesion to a PVC / PVC composite system, and the peel strength of the blank film sample can be improved to a level close to 2 times;. The fine-particle-size emulsion resin of the invention is expected to be applied to preparation of intaglioprinting water-based ink for ASA plastic films or PVC furniture films.

Description

technical field [0001] The invention relates to a water-based ink resin and a preparation method thereof, in particular to an emulsion resin that can be applied to an ASA plastic film water-based ink and a preparation method thereof. The resin of the present invention can be applied to an ASA plastic film gravure printing water-based ink, and can also be applied to PVC Water-based ink for furniture film gravure printing. Background technique [0002] Butyl acrylate-styrene-acrylonitrile (Acrylate-Styrene-Acrylonitrile) copolymer is called ASA resin or AAS resin for short. ASA has a similar structure to ABS, except that butadiene containing unsaturated double bonds is replaced by butyl acrylate with saturated structure, so ASA resin has better weather resistance. The excellent weather resistance of ASA resin allows it to be exposed to the outdoors for a long time without changing color, and can withstand harsh weather conditions such as wind, sun, rain, etc., so it is often ...
